"I think she found this difficult, which is why I have said many times, Harry and Meghan should have lived together for a bit, so she could see how things were done, not a rush to the chapel, she said.
Meghan Markle and Prince Harry stepped down from their royal duties a couple of years after getting married.
The couple is now living in the United States with their two children. Meghan is often blamed for Harry's decision to part ways with his family.
